Help: Singstar PS3 investigation

Hi,

I'm currently thinking of investigating how singstar on ps3 package their songs which you buy from the online store!. Once you purchase them you can download them as many times as you want (from what i know so far). One you download it, it just adds to your song library. But i was just starting to get into this tonight, Does any dev know how they package these songs? is it the same as normal demos PKG?. Any further assistance/insight...would help...

@idone...
i've tried to grab the file with ps3proxy but no fun at the moment...
only at start of game does it search for a update file (hits sony servers) but apart from that the re-download of the game i cannot find a proxy link?! this is using ps3proxy. what are your thoughts?
only update is looked for?!

been looking further into this...
it does show an "install screen" acutually "updating songs" now it does show a % out of 100 to show install. i'm having trouble using wireshark but nothing time will sort out!. but yeah guess already this file still is transmitted as a PKG file. but maybe not?

As far as I can tell, all PS3 installable data from the PSN comes in the same PKG format. For example, the Burnout stuff - which is all in the game update, except some unlocking data - still is a .pkg file when downloaded, though it's a download of 100 KB.
